Another Chipotle health crisis is brewing. A restaurant in Virginia is closed after a series of reports saying customers got violently ill, reports Business Insider. Symptoms include “vomiting, diarrhea, severe stomach pain, dehydration, and nausea,” which Chipotle toldBI is consistent with norovirus. The company adds that this means it did not come from its food supply. Nonetheless, Chipotle’s stock is dropping. It is currently down over 6%, at a price of $367.39 per share compared to its opening of $395.25.

This is exactly what Chipotle doesn’t need. For a refresher on the food safety issues that derailed the company’s trajectory, check out our long read from last year.
